So these drives are the cheapest for a 2TB drive.. and was wondering if it is okay (are there any known problems etc..) to put two of these into a Synology D212J NAS? And which one of the two I should get?

Drive 1 (Planning to get this one as they are actually in-stock): Link

Drive 2: (Are they basically the same thing? No stock for this one and model numbers are different to drive 1): Link
